Example on Mac OS X

OS X supplies python with the operating system so you shouldn’t need to install

To prevent overwriting important system files, it’s best to create a working
folder: a new empty folder somewhere and do all your testing in that folder.
For this example, create a folder called atrtest in your Documents
folder. Put a few disk images in this directory to use for testing.

Download or copy the file atrcopy.py and put it the Documents/atrtest
folder.

Since this is a command line programe, you must start a Terminal by double
clicking on Terminal.app in the Applications/Utilities folder in
the Finder. When Terminal opens, it will put you in your home folder
automatically. Go to the atrtest folder by typing:

cd Documents/atrtest

You should see the file atrcopy.py as well as the other ATR images you
placed in this directory by using the command:
